Baxi Duo Tec 28 Hot Water Issue.
Hi, I have a Nazi duo tec 28. I’m having an issue with my hot water.
If the CH is on, and I turn on the hot water I get warm/tepid water provided the HW temperature dial is set about 3o’clock.
If it’s set any higher, I get an E28 fault, and my water goes cold. If the CH is not on and I demand HW I get the E28 fault almost straight away.
The condense and flue can’t be blocked, otherwise I would have no CH. The flue and hot water thermistors have both been changed.
It’s recently had a new gas valve fitted. Baxi won’t touch it due to having to work on loft ladders.
Any help would be greatly appreciated.
Thanks,
Geoff
